This paper reports on RatDemo, an example program for the application of RatImage, the Research Assistance Toolbox for computerized human behavior experiments. The complete source code of this short experiment program is listed and briefly discussed. Since RatDemo combines several central...

This paper reports on RatImage, version 3.30. The extended features are presented. RatImage 3.30 is fully downward compatible to the first published version of the Research Assistance Toolbox for Computer-Aided Human Behaivor experiments, RatImage 3.10. This paper is an addendum to the manula of...

On the basis of experimental evidence reported in the literature the paper draws conclusions about the bounded rationality exhibited by human economic behaviour. Among the topics discussed are presentation effects caused by superficial analysis, strategic reasoning and strategy construction...

Essential characteristics of corruption are (1) a reciprocity relationship between briber and public official, (2) negative welfare effects, and (3) high penalties when discovered. We separate the influences of these factors in an experiment. In a two-player game reciprocation is economically...

In the economic literature on market competition, firms are often modeled as single decision makers and the internal organization of the firm is neglected (unitary player assumption). However, as the literature on strategic delegation suggests, one can not generally expect that the behavior of...

We use an experiment to explore how subjects learn to play against computers which are programmed to follow one of a number of standard learning algorithms. The learning theories are (unbeknown to subjects) a best response process, fictitious play, imitation, reinforcement learning, and a trial...

In this paper we investigate how the competitiveness of Cournot markets varies with the number of firms in an industry. We review previous Cournot experiments in the literature. Additionally, we conduct a new series of experiments studying oligopolies with two, three, four, and five firms in a...

In spring 2000, the British government auctioned off licences for Third Generation mobile telecommunications services. In the preparation of the auction, two designs involving each a hybrid of an English and a sealed-bid auction were suggested by the government: a discriminatory and a uniform...

Holmström’s (1982/99) career concerns model has become an important workhorse for the analysis of agency issues in many fields. The underlying signal jamming argument requires players to use information in a Bayesian way – which may or may not reasonably approximate real-life decision...

This paper reports on RatImage, a toolbox specifically developed to simplify the programming of software used in computerized human behavior experiments. RatImage contains Borland Turbo Pascal constans, variables, functions, and procedures which, when used, relieve programmers of many tedious...
